Here's a way to test it:

<?php

$a = range(0,4);

foreach($a as $k => $v){
if(isset($a)) unset($a);
echo "$k => $v<br>";
}

print_r($a);

?>

To me it would seem the entire array is copied, since it prints all the
values even after the array is unset, I got the output:
0 => 0
1 => 1
2 => 2
3 => 3
4 => 4
